History proves that government more often than not fails to take actions necessary to prevent disaster. They only know how to react after the fact. Politicians keep them neutered against groups that some of their campaign donors covertly support. That's why if you ask any democrat today, nearly all downplay the violence of the left. Some deny it even exists. They do this because they are just salesmen being paid to sell that line. Who could possibly want to cause riots and domestic conflict in America?
